Cprnout() sends one character to GemDos handle 3 (normally 'prn:').

5 (0x05)

All GemDos versions.

ch is a WORD value, however, only the lower 8 bits are sent to the output stream. The upper eight bits should be 0.

	move.w  ch,-(sp)
	move.w  #$5,-(sp)
	trap    #1
	addq.l  #4,sp

Cprnout() returns a non-zero value if the function successfully wrote the character to the printer or 0 otherwise.

No input translation is performed with this call. Therefore, you must send an ASCII 13 and ASCII 10 to force a new line.
